Re-examining beetle specimens from 19 museums has led to the discovery of 84 new beetle species in the Macratria genus. The new species span the islands of Indonesia, New Guinea, and the Solomon Islands, tripling the number of known Macratria beetles in the region. "Species of the genus Macratria are cosmopolitan, with the highest species diversity in the tropical rainforests. Only 28 species of this genus were previously known from the territory of the Indo-Australian transition," Dr. Dmitry Telnov with the Entomological Society of Latvia, who discovered the new species, told mongabay.com.
